Inductance tolerance: ±20% (acceptable range)
Current rating: minimum 1.1 A
DC resistance: maximum 288 mOhm preferred, with tolerance for slight increases
Shielding configuration: unshielded (to maintain electromagnetic compatibility)
Core type: drum core wirewound with ferrite material
Mounting type: surface mount
Operating temperature range: minimum -40°C to 100°C coverage

Frequently Asked Questions (FAQ)

Q: Can I use P0752.104NLT as a direct replacement for CDR95NP-101MC?

A: Yes. P0752.104NLT meets all critical electrical parameters: 100 µH inductance, 1.2 A current rating (exceeds 1.1 A requirement), and unshielded configuration. The 380 mOhm DC resistance is higher than the 288 mOhm specification but acceptable for most applications. Physical dimensions are nearly identical. Verify PCB layout compatibility before implementation.

Q: What is the difference between ASPI-0804T-101M-T and ASPI-104S-101M-T?

A: ASPI-0804T-101M-T is unshielded with a current rating of 1.2 A and 280 mOhm DCR. ASPI-104S-101M-T is shielded with a current rating of 1.25 A and 304 mOhm DCR. The shielded variant reduces electromagnetic coupling to adjacent components but increases physical size. Select based on EMI requirements and available PCB space.

Q: Why does SDR1045-101K have such high DC resistance compared to other options?

A: SDR1045-101K has a DC resistance of 540 mOhm, which is significantly higher than the CDR95NP-101MC specification of 288 mOhm. This results from its smaller physical footprint (10.00 × 10.00 × 4.80 mm). Use this part only when space constraints outweigh power dissipation concerns, or when the application can tolerate increased resistive losses.

Q: Is the operating temperature range critical for substitution?

A: The CDR95NP-101MC operates from -40°C to 100°C. Most substitute parts extend this range to 125°C or higher, providing additional thermal margin. Parts with reduced upper temperature limits (such as ASPI-0804T-101M-T and ASPI-104S-101M-T at 85°C) are suitable only if your application does not exceed 85°C. Verify thermal requirements before selection.

Q: Can I use UP2B-101-R if my PCB layout is space-constrained?

A: UP2B-101-R has larger physical dimensions (13.97 × 10.41 × 6.00 mm) compared to the CDR95NP-101MC (12.90 × 9.40 × 5.20 mm). This part is not suitable for space-constrained applications. Consider SDR1045-101K (10.00 × 10.00 × 4.80 mm) or ASPI-104S-101M-T (10.10 × 10.00 × 4.00 mm) for reduced footprint requirements.

Q: What does MSL 1 rating mean for handling and storage?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without special moisture control. All listed substitute parts carry MSL 1 rating, matching the original CDR95NP-101MC. Standard dry storage conditions are sufficient; no special desiccant or humidity-controlled storage is required.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant, matching the environmental compliance status of the CDR95NP-101MC. This ensures compatibility with RoHS3-regulated applications and supply chains.

Q: What is the significance of inductance tolerance ±10% versus ±20%?

A: CDR95NP-101MC has ±20% tolerance. SDR1005-101KL and SDR1045-101K have ±10% tolerance, providing tighter inductance control. Tighter tolerance is beneficial for precision applications but not required for general-purpose use. Both tolerance levels are acceptable for substitution unless your circuit design specifies tighter tolerance requirements.

Q: Why is the current saturation (Isat) parameter important?

A: Isat indicates the current level at which the inductor's inductance begins to degrade due to core saturation. CDR95NP-101MC has Isat of 1.4 A, providing margin above the 1.1 A continuous rating. Most substitutes maintain similar or higher Isat values, ensuring stable performance under transient current conditions. UP2B-101-R has lower Isat (950 mA), limiting its use in applications with current transients exceeding this level.
